When defeated, he breaks apart and shatters, like a broken mirror. His appearance is similar to that of Meta Knight, but is different in coloration.His skin is gray, his cape is tattered, and his eyes are more slanted. also, in an official artwork, it is shown that he has a scar over his left eye on his mask. The sword he wields is a copy of Galaxia, the difference being that it is silver, instead of gold and the hooks are square shaped. He has a different mindset than the real Meta Knight, not only never or hardly showing honor, but is nothing but pure, conceited evil.
Kirby & The Amazing Mirror
